In CM8000 the hash table size is one of the GUI options available whenever you
set up a personality. So nothing special is required.
With CM6000 you must edit the cm.ini file with an editor such as Notepad. Change
the value of ttable_size= according to how much hash you want, which must be in
multiples of 2. It must be somewhat less than your available RAM because your
op system needs some RAM too (probably at least 32MB). If you have selected too
much hash, your hard drive will grind constantly and not stop. It's normal for
it to grind for a minute or so if you are near the limit, but then it should
stop with only an occasional click.
ttable_size=19 hash 0.5MB
ttable_size=20 hash 1MB (default)
ttable_size=21 hash 2MB
ttable_size=22 hash 4MB
ttable_size=23 hash 8MB
ttable_size=24 hash 16MB
ttable_size=25 hash 32MB
ttable_size=26 hash 64MB
ttable_size=27 hash 128MB
ttable_size=28 hash 256MB
I have 192MB RAM so could use 128MB hash, but find 64MB hash more practical if I
want to multitask with other software. For example I can run CM6000 and Hiarcs
7.32 simultaneously, each with 64MB hash, although of course they slow each
other down.
